What is the cause of the most basic and obvious changes in the appearance of celestial objects: rotation of the earth. If you are stuck on earth, how can you tell the earth is rotating: foucault pendulum, coriolis effect. Why does the amount of daylight change throughout the year: due to earth"s tilt with respect to the sun. Why do we see different stars at night at different times of the year: star pattern rotates around us every 23 hours 56 minutes due to earth"s tilt.
